Description

Die Erfindung betrifft ein Fahrzeug mit einer Einrichtung zur passiven Berechtigungskontrolle, wobei die Einrichtung Ultra-Breitband-Antennenvorrichtungen aufweist, über welche die Einrichtung mit einem elektronischen Schlüssel zur Prüfung einer Berechtigung für einen Zugang, eine Aktivierung einer Funktion oder einen Start des Fahrzeugs kommunizieren kann.The invention relates to a vehicle having a passive authorization control device, the device comprising ultra-wideband antenna devices through which the device can communicate with an electronic key for checking authorization for access, activation of a function or launch of the vehicle.

Aus dem Dokument EP 2 800 068 A2 ist ein Fahrzeug mit einer Einrichtung zur passiven Berechtigungskontrolle bekannt, die mehrere Ultra-Breitband-Antennenvorrichtungen aufweist. Über die Antennenvorrichtungen kann die Einrichtung zur passiven Berechtigungskontrolle mit einem elektronischen Schlüssel zur Prüfung von Berechtigungen kommunizieren. Das Dokument EP 2 800 068 A2 beschäftigt sich hauptsächlich mit Mechanismen zur Verhinderung von sogenannten Ralais-Attacken, die zum Diebstahl von Fahrzeugen mit sogenannten PassiveEntry/PassiveGo-Systemen verwendet werden können.From the document EP 2 800 068 A2 For example, a vehicle is known having a passive authorization control device that includes a plurality of ultra wideband antenna devices. Through the antenna devices, the passive authorization control device can communicate with an electronic key for checking permissions. The document EP 2 800 068 A2 deals mainly with mechanisms for preventing so-called ralais attacks, which can be used to steal vehicles with so-called PassiveEntry / PassiveGo systems.

Die Verwendung von Ultra-Breitband-Signalen zur passiven Berechtigungskontrolle ist noch nicht verbreitet und wurde von der Anmelderin daher untersucht. Es hat sich herausgestellt, dass die bisherigen Konzepte von Einrichtungen zur passiven Berechtigungskontrolle für die Verwendung mit Ultra-Breitband-Signalen weiterentwickelt werden müssen, damit gute Ergebnisse erzielt werden.The use of ultra wideband passive authorization control signals is not yet widespread and has therefore been investigated by the Applicant. It has been found that existing concepts of passive authorization control equipment for use with ultra-wideband signals need to be developed further in order to achieve good results.

So hat sich zum Beispiel herausgestellt, dass es Probleme mit der Abdeckung der unmittelbaren Umgebung des Fahrzeugs mit Signalen der Ultra-Breitband-Antennenvorrichtungen geben kann. So werden die Bereiche in der unmittelbaren Umgebung des Fahrzeugs nicht gleichmäßig abgedeckt. Das kann dazu führen, dass die Signale der Ultra-Breitband-Antennenvorrichtungen einen elektronischen Schlüssel in der Umgebung nicht erreichen und eine passive Berechtigungskontrolle nicht erfolgen kann.For example, it has been found that there may be problems with coverage of the immediate surroundings of the vehicle with signals from the ultra-wideband antenna devices. Thus, the areas in the immediate vicinity of the vehicle are not uniformly covered. This may result in the signals of the ultra-wideband antenna devices not reaching an electronic key in the environment and passive authorization control not being possible.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass zumindest eine der Antennenvorrichtungen wenigstens einen Reflektor aufweist, der im Abstand von einer Ultra-Breitband-Antenne der Antennenvorrichtung angeordnet ist. Durch die Anordnung eines Reflektors in der Antennenvorrichtung ist es besser als bisher möglich, dafür zu sorgen, dass Signale der Antenne in gewünschte Richtungen gelenkt werden. Anstelle von bisher unkontrollierten Reflektionen an Teilen der Karosserie oder anderen Teilen des Fahrzeugs treten nun bei einem erfindungsgemäßen Fahrzeug Reflektionen auf, die über den Reflektor eingestellt oder zumindest beeinflusst sind, so dass in dem Bereich der Antennenvorrichtung eine weitgehend gleichmäßige und lückenlose Abdeckung durch die von der Antennenvorrichtung gesendeten Signale erreicht werden kann.This problem is solved according to the invention in that at least one of the antenna devices has at least one reflector which is arranged at a distance from an ultra-wideband antenna of the antenna device. By arranging a reflector in the antenna device, it is better than hitherto possible to ensure that signals of the antenna are directed in desired directions. Instead of hitherto uncontrolled reflections on parts of the body or other parts of the vehicle reflections occur in a vehicle according to the invention, which are set or at least influenced by the reflector, so that in the area of the antenna device, a largely uniform and gapless coverage by the of Antenna device transmitted signals can be achieved.

Der Reflektor kann eine Reflektorplatte sein oder eine Reflektorplatte umfassen. Es ist möglich, dass der Reflektor ein Teil der Karosserie des Fahrzeugs ist oder einen Teil der Karosserie des Fahrzeugs bildet. Die Karosserie weist dann einen besonderen Bereich auf, der als Reflektor gestaltet ist, um das gewünschte Verhalten der Antennenvorrichtung zu erhalten.The reflector may be a reflector plate or comprise a reflector plate. It is possible that the reflector is a part of the body of the vehicle or forms part of the body of the vehicle. The body then has a particular area designed as a reflector to obtain the desired behavior of the antenna device.

Eine Antennenvorrichtung eines erfindungsgemäßen Fahrzeugs kann ein Gehäuse aufweisen. Der Reflektor kann im Gehäuse, durch eine Gehäusewand und an einer Gehäusewand ausgebildet sein. Der Reflektor kann beispielsweise eine galvanische Beschichtung einer Gehäusewand sein.An antenna device of a vehicle according to the invention may have a housing. The reflector may be formed in the housing, by a housing wall and on a housing wall. The reflector may be, for example, a galvanic coating of a housing wall.

Der Reflektor kann im Grunde jede Form haben. Er kann insbesondere plan sein oder gewölbt sein.The reflector can basically have any shape. In particular, it can be flat or curved.

Es hat sich herausgestellt, dass es besonders vorteilhaft ist, wenn die Antenne und der ihr zugeordnete Reflektor einen Abstand von ca. 5 mm bis 30 mm, insbesondere ca. 15 mm bis 30 mm, z.B. ca. 10 mm aufweisen.It has been found that it is particularly advantageous if the antenna and its associated reflector have a distance of about 5 mm to 30 mm, in particular about 15 mm to 30 mm, e.g. about 10 mm.

In einem erfindungsgemäßen Fahrzeug können mehrere Antennenvorrichtungen vorgesehen sein. Es ist möglich, dass die Antennenvorrichtung oder jede der Antennenvorrichtungen mehrere Antennen aufweist.In a vehicle according to the invention, a plurality of antenna devices can be provided. It is possible that the antenna device or each of the antenna devices has a plurality of antennas.

Die Antenne oder die Antennen einer Antennenvorrichtung können zur Aussendung von linear polarisierten UWB-Signalen geeignet und eingerichtet sein.The antenna or antennas of an antenna device may be suitable and arranged for the transmission of linearly polarized UWB signals.

Ein elektronischer Schlüssel für das erfindungsgemäße Fahrzeug oder ein anderes geeignetes Fahrzeug kann eine Antenne für linear polarisierte UWB-Signale aufweisen. Das hat gegenüber einer Antenne für zirkular polarisierte Signale den Vorteil, dass die Antenne kleiner sein kann und weniger Fläche und/oder Bauraum in Anspruch nimmt. Die Antenne eines solchen Schlüssels kann ein Stanz-Biegeteil sein. Durch einfache Anpassungen des Stanz-Biegeteils ist es möglich, die Antennen auf einen bevorzugten Frequenzbereich einzustellen. Ein Teil des Stanz-Biegeteils kann ein dreieckiger oder gerundeter Monopole sein. Insbesondere mit einem gerundeten Monopole kann eine große Bandbreite erreicht werden. Durch die Verwendung eines Stanz-Biegeteils anstelle einer auf einem Schaltungsträger durch Leiterbahnen ausgebildeten Antenne kann der Platzbedarf für die Antenne reduziert werden. Auch im Vergleich zu einer keramischen SMD-Antenne gibt es Vorteile, nämlich die größere Robustheit des Stanz-Biegeteils im Vergleich zu einer keramischen Antenne.An electronic key for the vehicle of the invention or another suitable vehicle may comprise an antenna for linearly polarized UWB signals. This has the advantage over an antenna for circularly polarized signals that the antenna can be smaller and takes up less space and / or installation space. The antenna of such a key may be a stamped and bent part. By simple adjustments of the stamped and bent part, it is possible to set the antennas to a preferred frequency range. A part of the stamped and bent part may be a triangular or rounded monopole. Especially with a rounded monopole, a wide bandwidth can be achieved. By using a stamped and bent part instead of an antenna formed on a circuit carrier by conductor tracks, the space required for the antenna can be reduced. Also compared to a ceramic SMD antenna, there are Advantages, namely the greater robustness of the stamped and bent part compared to a ceramic antenna.
